Ingredients:
- 250g Digestive Biscuits (or Graham Crackers)
- 115g Unsalted Butter (Melted)
- 50g Granulated Sugar (for crust)
- 1/4 tsp Salt (for crust)
- 900g Full-Fat Cream Cheese (Room Temperature)
- 300g Granulated Sugar (for filling)
- 4 Large Eggs (Room Temperature)
- 1 Extra Egg Yolk
- 120g Full Fat Sour Cream (Room Temperature)
- 60ml Heavy Cream (35% or higher)
- 2 tsp Vanilla Extract
- 1 tsp Lemon Zest (Fine)
- 2 tbsp All-Purpose Flour (Sifted)
Instructions:
- Preheat oven to 350°F (175°C). Wrap the exterior base and sides of the 9-inch springform pan securely with 2-3 layers of heavy-duty foil to prevent water leakage.
- Make the Crust: Pulse biscuits/crackers into fine crumbs. Combine crumbs, 50g sugar, and salt. Drizzle in melted butter and mix until the texture resembles wet sand.
- Press the crust mixture firmly and evenly into the bottom of the prepared pan. Chill for at least 30 minutes.
- Create the Filling: In a large bowl, beat the softened cream cheese until completely smooth, scraping down the sides frequently.
- Gradually beat in the 300g sugar until just combined and smooth. Beat in sour cream, heavy cream, vanilla, and lemon zest until homogenous.
- Add eggs one at a time, mixing only until the yolk disappears after each addition. Stop mixing immediately once the last egg is incorporated to avoid incorporating excess air.
- Pour the batter over the chilled crust. Gently tap the pan on the counter a few times to release any large air bubbles.
- Set up the Water Bath: Place the foil-wrapped springform pan inside a larger roasting pan. Place this setup onto the middle oven rack.
- Carefully pour boiling water into the roasting pan until it reaches about halfway up the sides of the springform pan (the bain-marie).
- Bake for 60-75 minutes. The edges should look set, but the centre (a 2-inch circle) should still have a slight wobble.
- Cooling Phase 1: Turn off the oven. Prop the oven door open a crack (using a wooden spoon handle) and allow the cheesecake to cool inside the turned-off oven for 1 hour.
- Cooling Phase 2: Remove from the water bath, remove the foil, and let it cool on a wire rack to room temperature (about 1 hour more).
- Cover loosely with plastic wrap and chill in the refrigerator for a minimum of 8 hours, or preferably overnight, before slicing and serving.
